Each hutch is equipped with a Hutch Search Message which sounds
while the hutch is being searched. The message starts as soon as
you initiate a search of the hutch (by pressing the green button
on the first search box).
The message consists of a red flashing light as seen at the right,
as well as a computerized voice that instructs anyone in the hutch
to leave. For example, if you are searching hutch C, the voice will
repeat: "Searching Section C, Exit Immediately."
